📌 Quick 30-Second Summary (Snippet Bait):
A Systems Administrator (SysAdmin) maintains on-premise physical servers, local networks, and OS patches. A Cloud Engineer designs and optimizes cloud architectures on AWS/GCP/Azure. A DevOps Engineer bridges software development and IT operations by automating CI/CD pipelines, container orchestration, and Infrastructure as Code (IaC).
As enterprise IT transitioned from physical server rooms to multi-cloud architectures, infrastructure engineering evolved rapidly. In this guide from Careers Mentor, we explore the shift from traditional systems administration to modern Cloud and DevOps engineering.
